So has the EU collapsed spectacularly or turned into a federation yet?
I read in one of the PNAC manifestos that a European army would be an undesirable outcome for the US because it would undermine NATO...but with Brexit, the United States' eye into the EU is gone. Might progress accelerate under the next Trumpian president, or when the next election comes around?
A US-European split, or at least a decoupling, would be one of the more interesting events of the 21st century for sure. But I can't see it unless Russia either collapses or comes under fresh leadership that's willing to collaborate and that the US is willing to collaborate with on interests in the Middle East and against China.
